This invention relates to parquet constructions.

It is an object of the present invention to provide composite sections which may be made of various sizes and shapes, including parquet pieces, which may be quickly and easily laid on a cement base.

Other objects of the present invention are to provide a parquet construction which can be laid with little trouble and expense, wherein the elements are of simple construction, provide insulation, rodent and termite proof, inexpensive to manufacture, durable and of long life.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view of a portion of a floor formed with parquet pieces arranged according to one pattern,

Fig. 2 is a perspective view of a parquet construction with the pieces arranged according to another pattern,

Fig. 3 is a perspective view of a construction formed of parquet elements arranged in still a different manner,

Figs. 4, 5 and 6 are respectively enlarged fragmentary perspective views of the parquet construction shown respectively in Figs. 1, 2 and 3,

Fig. 7 is a top plan view of a parquet construction formed in still a. different manner,

Figs. 8 and 9 are respectively cross-sectional views, in elevation, taken on lines 88 and 9-3 respectively of Fig. 7,

Fig. 10 is a top plan view of the metal pieces forming a part of the parquet element,

Fig. 11 is a, side elevational view of the metal pieces,

Fig. 12 is an enlarged fragmentary corner portion of the metal piece,

Fig. 13 is a fragmentary view of the metal pieces, in section, with the parquet wood pieces elevated above the prongs of the metal pieces but separated therefrom,

Fig. 14 is a fragmentary cross-sectional view taken on lines l4-l4 of Fig. 13.

Referring now to the figures, and more particularly to Figs. 1 and 4, there is shown a parquet construction formed of parquet elements l5 which are rested on a solid cement base IS in a soft cement layer which hardens to retain the elements. The parquet elements l5 have short and long pieces ll and i8 and are spaced from one another as indicated at l9. The wood pieces I! and I8 are recessed at their bottom edges to better receive filling material, such as magnesite compo- 2 sition. Between the parquet elements are spaces 21 and between groups of four parquet elements are large spaces 22.

Referring now to Figs. 2 and 5, each parquet element 23 has three long parquet wood pieces 25 having tongue and groove connections between them. The elements 23 are arranged in groups of four and the elements in the group are separated by spaces 23 and the groups are separated by large spaces 21.

Referring now to Figs. 3 and 6, the parquet elements themselves are the same as that shown in Figs. 2 and 5, but when the elements are assembled upon the base l6, they are closed upon one another to a tongue and groove connection therebetween. The large spaces 21 are provided between the groups of four.

In Figs. 7 and 8, there is shown a still further construction wherein each parquet element is formed of four pairs of short wood pieces 3| separated from one another by spaces 32. Each parquet block itself is separated from one another by spaces 33. The spaces 32 and 33 fill undercut recesses 34 of the piece 3|.

Elach parquet element or block in this last mentioned construction, as well as the previously mentioned elements, includes a metal box like structure 35 having holes 36 in the sides of the same and top holes formed by striking outwardly pointed triangular shaped projections 37 adapted to pierce wood elements to retain the wood elements in place against lateral and vertical displacement, Figs. 10 to 14. Struck up projections or lugs 38 are provided in spaces 32 and 33. The metal structures 35 are filled with soft cement mortar 39 as the elements, comprising the metal structure 35' and the Wood pieces are pressed into the same upon being assembled upon the floor base 4|. The parquet wood pieces 3| are preferably formed with holes 43 to receive the upwardly struck projections or teeth 31, Figs. 13 and 14.

After the parquet elements have been assembled upon the floor base and the cement mortar has hardened, a, filler of magnesite composition is worked into all spaces. Thereafter, when the filler has set, the whole floor is scraped, sanded and waxed.

While various designs and arrangements of the parquet wood pieces may be had and various detail changes may be made in the construction of the parquet blocks, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

3 I claim: In a floor for a building construction, a horizontally disposed concrete base, a plurality of metal box-like apertured members positioned on 4 said lugs, and further spacer strips contacting the base and positioned between the metal box-like members, and tongue and groove connections between the last named spacer strips and the floor said base, a plurality of circular sets of pointed 5 pieces.

teeth extending upwardly from said members and formed integral therewith, a plurality of triangular shaped inclined pointed lugs extending upwardly from said members and positioned between said. circular sets of teeth, a plurality of wooden floor pieces mounted on said box-like members, each of said floor pieces being provided with circular openings in their lower surface to receive said teeth, spacer strips interposed between the individual floor pieces and engaged by 15 2,089,550
